PUMP ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 16, 1917.

Application filed April 26, 1916. Serial No. 93,722.

J '0 all whom it may concern:

Be it known that I, WVILLIAM L. SAN- rono, a citizen of the United States, residing at Clayton, in the county of Polk and State of Wisconsin, have invented certain useful Improvements in Pump Attachments, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in pumps, and relates more particularly to an attachment whereby the drain openings in the standpipe of a pump may be opened or closed without necessitating the removal of the standpipe from the well.

A further object of this invention is the provision of a simple, durable and inexpensive device of this character which is readily attached to the standpipe of any pump and which is thoroughly eflicient and practical in use.

In the accompanying drawings:

Figure 1 is an elevation of a standpipe equipped with the present invention.

Fig. 2 is a cross section taken on line 2-2 of Fig. 1.

Fig. 3 is a View in elevation of the device per se.

Fig. 4 is a detail view of the valve per 86.

Referring to the drawings, the numeral 5 designates the standpipe which is provided with the drain outlet 6. Adapted to surround the standpipe is the band or ring 7 which is provided with the flexible flanges 8 and 9 at the respective terminals thereof, which are adapted to be secured together by means of bolts 10, so that the band may be clamped upon the standpipe.

Formed integrally with the band and projecting exteri rly therefrom is a tubular projection 11 which is provided with a port' 12 alined with the outlet 6. Adapted to slide within the projection and be incased thereby and also by the standpipe is a cylindrical valve 13 which is provided with the pin 14. that cooperates with the shoulders 15 to limit the rotation of the valve.

The valve 13 is provided with the bore 13 opening at the lever end, and having a port 13 for alinement with the port 12. The lugs 15 receive the rod 16, by means of which the valve may be oscillated.

A sleeve 17 is fitted upon the pump base, and through this sleeve is mounted the operating rod 16, having thehandle 16.

Where the present device is made complete with the pump, the sleeve 17 will be made integral therewith, but where the device is applied to pumps now in use, an opening will be bored in the base to receive the sleeve.

What I claim as new is In a device of the kind described, in combination, a stand pipe, a band composed of two half ring sections hinged together and having flat flanges attached together so that said sections may clamp said stand pipe, one of said ring sections being formed with a tubular projection having a port communicating with the opening of said band, said stand pipe also having a port registering with said first port, a cylindrical valve rotatably projecting through said tubular projection, said projection being cut away at its lower end so as to provide a segmental recess, the back edge of which forms opposing shoulders, a pin secured at right angles upon the lower projecting end of said tubular projection, a flange on the upper end of said valve rotatably resting upon said proj ection, said pin playing between said shoulders, and an upright handle rod secured to said valve to effect its rotation.

In testimony whereof I affix my signature.

WILLIAM L. SANFORD.
